Question

On which factors does the magnetic field due to a current-carrying solenoid depend?

Hint:

A solenoid acts as a bar magnet when current flows through it. The magnetic field inside is strong and uniform.

Answer 1

The magnetic field inside a current-carrying solenoid depends on:
1. Number of turns (N): More turns increase the field strength.
2. Current (I): Higher current increases the field.
3. Core Material: Using soft iron as the core increases the magnetic field.
